Abstract
This thesis investigates novel ways of using wide area synchrophasor measurements for implementing response-based emergency control operations. Two synchrophasor measurement based Remedial Action Schemes (RASs), one to prevent cascaded tripping of transmission lines due to overloading when a major tie-line exporting power is tripped and the other to prevent uncontrolled islanding and blackouts due to transient instability, were developed. The RAS proposed for overload prevention in Manitoba Hydro grid acts to quickly reduce the power delivered from HVdc converters during the tripping of tie-lines exporting power to USA. The second RAS performs controlled islanding to prevent transient instability.
